I MPRovnMENT 1N .HYDRAN'rs To all whom 'it lina/y conce/rn:

Be it known that I, MICHAEL Zwnnr., of Pottsville, in the county of Schuylkill, and in the State of Pennsylvania, have invented new and useful Improveandj-d'ov hereby declare that the following is afull, clear, and exact description thereof', reference being had to the accompanying drawings,

through the casing B, is screwed to the upper end of the pipe H. i v

The nozzle I and pipe H are then securely fastened to the case B, by means of a jam-n ut, e.

The hydrant-rod J, which passes upthrough the centre of the cap O, is, at its lower end, provided with awrench, K, which fits on the key L of the hydrant- 'st'op and at its upper end the said rod has a handle, M, by means of which the hydrant is opened and closed.

At a suitablepoint on the hydrant-rod J is placed a collar, t, or other suitable projection, which works against the inner side, or rather the upper inner side of the cap C,t hereby protecting the key L from escaping from the wrench t.

v The nature of my invention 'consists in the construe# Y tion and general arrangement of a hydrant, as will be hereinafter fully ,set forth.

In order to enable others skilled in the art to which my invention appertain's, to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this specification, and in which Figure 1 isa vertical section of my hydrant, and

. Figure 2 is a perspective of a wrench used to take the samey apart. y

A represents the post orgbottom of hydrant-stock, made of cast-iron, or other suitable substantial material, and is to be placed permanently inthe ground.

Around the upper end of the post A- is a recess to receive the case or upper part, B,of hydrant-stock, which isalso made of cast-iron, or other suitable material"and provided, around the lower en d, with a small projection, a', to tit on and inthe recess on'the upper end ofthe post, to which it is securely fastened by one or more set-screws. b, bolt,4 rivet, or other suitablev means. j

The cap G of the hydrant is fastened tothe case B in the same mannerl that the casev is 'fastened to the post. t v V y p 'Io the bottom of the hydrant-post A is secured a a nipple, E, with female screw, said' nipple being attach-ed to the pipe leading to the' street-main.l l

F represents the hydrant-stop, which, on its lower end,`is provided with screw-threads tobe screwed into the nipple E, and is` protected from leaking at the joint by a leaden washer, c, being placed ,between the screws.

In the body of the hydrant-stop F'is a glass seat, d, solidly embedded with lead, or other suitable manner, to prevent the wearingof the seat by use, orby the leakage of waterwhich -is the 'case when metal'seats are used. y

In all vhydrants it is invariably `found that the seats in thc stop are soon worn out, so as to leak more or less. This is entirely bviated by theiuse of a glass seat, which is not as'liable to be wom olf byuse or by leakage.

To the hydrant-stop 1F is screwed to this elbow the hydrant-pipe H scribed, I am enabled to repair anypart of the pipe or stop by unscrewing the nozzle, taking'oi the cap and case of the hydrant, at a considerable less expense than in an ordinary hydrant, and avoiding the necessity of digging away the groundy from thehydrantconvenience. l

It will also be seen that when the nozzleis unscrewed and cap and casing taken off, the hydrant-stop and pipes can be removed, withoutdisturbing the post, by means of a wrench, the lower end of which I have represented in lig. 2. v

This wrench-has two arms 'or prongs ff, the lower ends of which are providedwith rounded slots. These forks or arms are placed, one on each side of the hydrant-stop F, one of said arms resting in its slot on the elbow G, and the other on a round projection on the opposite side of the stop. By then turning the handle of the wrench, the hydrant-stop can easily be unscrewed from the nipple E, taken out, repaired, and placed back in its position again.

' Having thus fully described my invention,

What I claim as new, and desire .to secure by Letters Patent, isa'- 1. In combination with the post A, casing B, cap O, bottom plate D, and nipple E,'the stop F, screwed into'the nipple E, and provided'with glass sea-td, the. elbow G, pipe H, and nozzle I, all constructed and ar-V ranged cooperate substantially as and for the pur- 'posesfs'etrv forth.

2. In combination with the subject-matter of the foregoing l clause, the keyd L, wrench K, and rod J, havinghandle M and collar t, all substantially as and for the purposes herein set forth. e hereunto set my hand, this 2d day of March, 1869.
